Article Abstract
In nature, ultrafast signal transfer based on ion transport, which is the foundation of biological processes, commonly works in a hydrogel-water mixed mechanism. Inspired by organisms' hydrogel-based system, we introduce hydrogel into nanofluidics to prepare a hydrogel hybrid membrane. The introduction of a space charged hydrogel improves the ion selectivity evidently. Also, a power generator based on the hydrogel hybrid membrane shows an excellent energy conversion property; a maximum power density up to 11.72 W/m is achieved at a 500-fold salinity gradient. Furthermore, the membrane shows excellent mechanical properties. These values are achievable, which indicates our membrane's huge potential applications in osmotic energy conversion.

Isotope-dependent Tafel analysis probes proton transfer kinetics during electrocatalytic water splitting.

Proton transfer plays an important role in both hydrogen and oxygen evolution reactions during electrocatalytic water splitting to produce green hydrogen. However, directly adapting the conventional proton/deuterium kinetic isotope effect to study proton transfer in heterogeneous electrocatalytic processes is challenging. Here we propose using the shift in the Tafel slope between protic and deuteric electrolytes, or the Tafel slope isotope effect, as an effective probe of proton transfer characteristics.

Decades of antibiotic misuse have spurred an antimicrobial resistance crisis, creating an urgent demand for alternative treatment options. Although phototherapy has therapeutic potential, the efficacy of the most advanced photosensitizers (PS) is essentially limited by aggregation-induced quenching, which significantly reduces their therapeutic effect. To address these challenges, we developed a cationic metallocovalent organic framework (CRuP-COF) via a solvent-mediated dual-reaction synthesis strategy.

Carbon dioxide enhanced oil recovery (CO-EOR) is widely used for carbon capture, utilization, and storage in Chinese oilfields, but part of injected CO returns with produced oil, reducing carbon-reduction efficiency. Bioconverting this CO to methane energy by methanogens benefits the technology, yet on-site high-efficiency conversion meeting natural-gas grid standards remains challenging. This study used a newly-designed triple-tank bioreactor to investigate CO-to-methane conversion and methanogenic kinetics of Methanococcus maripaludis.

This study explores highly active nitride-based g-CN/CuO photocatalysts for CO photoconversion by synthesizing them through high-pressure torsion (HPT) straining. Data indicate that increasing the applied strain under high pressure promotes vacancy formation and improves the electronic interaction at the g-CN/CuO interphases, enabling superior charge separation and extended light absorption. The generation of dual vacancies of oxygen and nitrogen is verified by electron paramagnetic resonance and Fourier transform infrared spectroscopic methods, and the generation of a type-II heterojunction is confirmed by band structure analysis.

Plant biomass has emerged as a cornerstone of the global bioenergy landscape because of its abundance and cost-effectiveness. The cell wall of plant biomass is an intricate network of cellulose, hemicellulose, and lignin. The hydrolysis of cellulose and hemicellulose by holoenzymes converts these polymers into monosaccharides and paves the way for the production of bioethanol and other bio-based products.
